decimal类型运算注意点

Posted 2020-10-07 江宁织造

代码如下：

 1             //货币类型的两个数基本运算
 2             Console.WriteLine("错误的写法");
 3             decimal errorNumA = (10 - 6);
 4             decimal errorNumb = errorNumA / 10;
 5             decimal errorNumC = (10 - 6) / 10;
 6 
 7             Console.WriteLine(errorNumb);
 8             Console.WriteLine(errorNumC);
 9 
10 
11             Console.WriteLine();
12             Console.WriteLine("正确的写法");
13             decimal numa = (10 - 6);
14             decimal numb = numa / 10m;
15 
16             decimal numc = (10 - 6) / 10m;
17 
18             Console.WriteLine(numb);
19             Console.WriteLine(numc);

运行结果：

运算的时候带m单位和不带结果大相径庭。切记、切记
